<h1>Macholib - Analyze and edit Mach-O headers<a class="headerlink" href="#macholib-analyze-and-edit-mach-o-headers" title="Permalink to this headline">¶</a></h1>
<p>macholib can be used to analyze and edit Mach-O headers, the executable
format used by Mac OS X.</p>
<p>It&#8217;s typically used as a dependency analysis tool, and also to rewrite dylib
references in Mach-O headers to be <tt class="docutils literal"><span class="pre">&#64;executable_path</span></tt> relative.</p>
<p>Though this tool targets a platform specific file format, it is pure python
code that is platform and endian independent.</p>
